In addition to the MassChallenge winners, the program’s partners awarded another $525,000 in sidecar prizes. The Center for the Advancement of Science in Space gave $75,000 to three companies, including Silverside Detectors, which also won $50,000 from MassChallenge and finished the night with the fattest overall purse: $125,000. Silverside makes low-cost radiation detectors designed to spot nuclear bombs in high-traffic areas like airports and subways.

Silverside Detectors is bringing to market a low cost radiation sensor that operates as a connected device for networks within and around cities. Sarah Haig enlightened us as to where this idea came from, how their detectors fit into the market, and what keeps them marching forward.
